We’ve grown a number of herbal thymes through the years, and most either take over the garden or die in our hot, humid summer. One that has really impressed us recently is the wonderful Thymus neiceffii, known as Juniper leaf thyme. This native to the Balkan peninsula forms a ground-hugging silvery mat that looks very much like a dwarf juniper, and is much more restrained in growth. Below is a spring image from our garden specimen, planted in our crevice garden and below that is an image from the garden in October. Hardiness is Zone 4b-9a.
